Since last Monday, all motions seeking liberty to enter a final judgment in summary summons proceedings must go before a High Court judge rather than the Master.
The decision has proved controversial and prompted a demonstration outside the Four Courts on Monday.
As of yesterday, more than 4,300 people had signed an online petition seeking the return of debt cases to the Master.
In the interview, Mr Honohan was also heavily critical of cuts to legal aid, saying the overriding agenda of the Government was not due process, but saving money.
Although not a judge, Mr Honohan is a senior counsel with a quasi-judicial role.
In contested cases he ensures correct procedures are followed and paperwork is in order before sending a matter on to the High Court....

He argues that while lawyers are familiar with the procedures, lay litigants are not and their affidavits are usually inadequate.
Mr Honohan claims that after he raised the issue in 2011, a High Court judge, who he did not name, warned the Irish Human Rights Commission against supporting him.
"They were told Honohan is a nutter," he said.
Mr Honohan said some affidavits from banks were "really offensive to my eye" as they "really seek to portray a defendant as misleading the court, a charlatan".
However, he denies being biased against financial institutions. "All I am doing is applying the rules across the board," he said.
Although "not as distressed and shocked as some people seem to think", he admitted being "quite annoyed" by Mr Justice Kelly's decision.
"What I am doing, in the absence of proper legal aid, is attempting to act in a Christian manner to defendants who want to know what they should do next. I ask them what their story is and I say: 'This is how you deal with it.'"
He now fears defendants might not get the same "care and attention" from a judge.
